Electricity is a must in everybody's home. Everyone knows that the circuit needs to be wired when the home circuit is running. Although the development of wire circuit technology is now very fast, there is still some danger. The consequences of leakage of the wire circuit can cause people to be injured, which can cause paralysis and even death. How to avoid the leakage of electricity in the wire circuit at home? It can be solved by a household leakage circuit breaker. Next, Xiaobian will briefly introduce the working principle of the household leakage circuit breaker and the connection method of the leakage circuit breaker.
First, the working principle of household leakage circuit breaker
Household leakage circuit breakers, as the name implies, are decorative devices that protect against leakage. They are also very important in home decoration. Of course, there are special devices in other occasions. When the current in the power supply exceeds the maximum current value set in advance, the household leakage circuit breaker will be automatically disconnected, which will serve as a protection power source to avoid unnecessary safety accidents. In the wiring diagram of the household leakage circuit breaker, there are zero line and live line. If there is no leakage, the direction of the live line and the neutral line are opposite and the current is equal. When there is leakage, the magnetic force will be generated and the current will be different. Disconnect the leakage circuit breaker to achieve the protection.
Buying and selling Baoshang supplier Siemens launched a family-specific leakage circuit breaker, which is green, environmentally friendly and energy-saving, and guarantees the safety of household electricity.
Second, the household leakage circuit breaker connection method
If you want to install such a power protection device, you must understand the wiring diagram of the household leakage circuit breaker in advance, and understand the meaning of the wiring diagram of the household leakage circuit breaker. In addition, when using household leakage circuit breaker equipment, it is also necessary to pay attention to many aspects. For example, after the household leakage circuit breaker is connected, the line should be inspected first, and the circuit equipment should be improved. The correctness of the household leakage circuit breaker equipment can be determined through trial. If there is any problem, the fault caused by the household leakage circuit breaker should be eliminated in time. In addition, it should be noted that the incoming fire and zero wire are connected to the front end of the leakage switch, the outgoing wire, the live wire is placed at the upper end of the ordinary open, the neutral wire is placed on the neutral terminal block, and the neutral wires of all the loads are placed on the terminal block. On the top, you can not take the zero line at the end of the line.
Third, household leakage circuit breaker matters needing attention
The overload, leakage and short circuit of the household leakage circuit breaker are specially set by the manufacturer. Therefore, in normal times, it cannot be adjusted at will, so as not to affect the normal use of the household leakage circuit breaker.
